SIṄGĀRŪ, BHĀĪ, and his brother Jaitā, both brave soldiers, received initiation at the hands of Gurū Arjan. The Gurū directed them to be in attendance upon his son, Hargobind. They continued to serve the latter and were happy to see him installed as Gurū in 1606. According to Bhāī Santokh Siṅgh, Srī Gur Pratāp Sūraj Granth, they were once on a visit to their native village when they were given by a yogī ash of mercury supposed to turn base metal into gold. They brought it as an offering for Gurū Hargobind. The Gurū, however, cast the ash into the pool, saying : "This is mere charlatanry for one who has reduced his ego to ashes. The ash of mercury might transform copper into gold, but the reduction of ego transforms man into God." Bhāī Siṅgārū and his brother ranked among the prominent Sikhs of the time. They also took part in Gurū Hargobind's battles with the Mughal troops.
